Tidal Current Tables

This system will allow you to calculate tidal current predictions for the more than 2700 tidal current stations predicted by CO-OPS. The publication of full daily predictions is necessarily limited to a comparatively small number of stations. These stations are refered to as "reference stations". The remaining stations are refered to as "subordinate stations". Tidal current predictions at the subordinate stations can be obtained by applying specific differences to the time and speed of maximum and minimum currents at a specified reference station.

These pages provide a listing of the more than 2700 subordinate stations for which predictions can be made, the differences for each, and a link to the appropriate reference station. The list of subordinate stations has been broken down into states and other areas for which there are tide stations. Each state is further broken into regions for your selection. Each region will present a list of the tidal current stations in the area. These stations have been listed geographically; thus stations which are near each other will be near each other in the listing. This will make finding the location you are interested in, or a nearby station, simpler.

Unlike tide stations, which are normally located along the shoreline, most tidal current stations are located offshore in the channels, rivers, and bays. Tidal current stations are often named for the channel, river, or bay in which they are located or for a near by navigational reference point. A map or some personal knowledge of the area may be necessary to help in identifying stations in the area you are interrested in.

Instructions on how to apply the time and height differences can be found by "clicking" on one of the

found in multiple places within the listing of subordinate stations.

For you convenience, the predicted times are given with Daylight Saving Time incorporated from April to October when appropriate. Speeds are provided in knots.
